if you're root, use the force:

 #!/bin/sh

 get_x_credentials()
 {
     # fetch the local X server's XAUTHORITY variable
     eval "$( xargs -n 1 -0 < /proc/$(pidof X)/environ | grep '^XAUTHORITY=')"
     export XAUTHORITY
     export DISPLAY=:0
 }

 test "$XAUTHORITY" || get_x_credentials

 sugar-control-panel -blah
